Application of entropy-ratio maps to surficial reef facies, Great Barrier Reef

Created 05/03/2026

Updated 05/03/2026

Entropy-ratio maps enable mapping of surficial facies of coral reefs at any chosen resolution. A ternary classification uses detritus, framework encrustation, and pavement as end-members, and is subdivided on the degree of mixing of these. The classification is sensitive to all reef environments, particularly to zonation across reef flats. It can also be superimposed on other classifications. An example is given of its use in the Great Barrier Reef.
